HYDRANT.

SPECIFICATION forming part of Letters Patent No. 574,744, dated January5, 1897.

Application'iiled December 12,1895. Serial No. 571,913. (No model.)

To all whom '1125 may coll/cern.-

Be it known that I, NEIL MALMQvIsT, a citizen of the United States, anda resident of Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in Hydra-nts, of whichthe following is a speciiication.

My invention consists of improvements in hydrants whereby it is designedto simplify the construction, cheapen the cost, and improve theoperation, as hereinafter described, reference being made to theaccompanying drawings, in which- Y.

Figure l is a sectional elevation of my improved hydrant, the sectionbeing taken on line as it, Fig. 2. Fig. 2 is a sectional elevation online y y, Fig. l. Fig. 3 is a top View. Fig. 4 is a horizontal sectionon line 2 2, Fig. 2. Fig. 5 is a horizontal section on line 23 3, Fig.2. Fig. G is a horizontal section on line et 4, Fig. 2; and Fig. 7 isahorizontal section on line 5 5, Fig. 2. Fig. S is a section of thewastevalve. 1

The stand-pipe a has an inlet-opening b for the water at one side nearthe lower end, and a valve-face c surrounds said opening on the outsideof the tube. This valve-face is inclosed in valve-chest d, bolted on, asat e, said chest being faced on the inside for a gate-valve 3o f andhaving the pipe-connecting nozzle g on the back for connection with thewater-main. On the back of the valve is a tubular packingfollower h,closely fitted in the bore of the nozzle and having springs t' to keepit in contact with the valve to prevent leaking into the box. The valveis connected to the rod j, which enters the valve-box through thestuffing-box k, and is secured by a pin Z, the joint being made a littleslack to favor 'close contact of the valve with the face c.

The stuffing-box for the valve-rod is formed on the end cover m of thevalve-chest, together with a protective guard-tube 1t for the valverod,extending to the top of the stand-pipe along and in contact with thestand-pipe and having flanges o atintervals along it for bolting on tocorresponding flanges p of the standpipe, said protective tube having aslot for the most part of its length on the side next to the stand-pipeand being faced to fit a corresponding face of the stand-pipe, as shownat q, sufficiently to exclude surface water and protect againstfreezing. In the top of this rod-protecting tube is a nut q', screwingon the rod, to open and close the valve, said nut being confined undercap s by the collar t and having a spur u extending up through the capfor the application of a wrench for turning the nut. The slot in theprotective tube facilitates inserting the valve-rod and adjusting thestuffing-box before 'said tube is attac-hed to the stand-pipe.

The stand-pipe a is closed at the top by a removable cover n, which maybe taken off to open the pipe for any purpose, and a hole w is madethrough the cover for inserting a rod which may sometimes be required tostir up any collections of matter that may settle in the bottom. Thehole will be closed by any suitable plug. The discharge-nozzles areformed onv the stand-pipe near the top.

Over the waste-valve d', employed for the discharge of the waterremaining in the standpipe a after the valve f is closed, I provide aprotective case b', inclosing it in a chamber of larger. dimensions thanthe case of said valve to prevent it from being clogged with soil, whichwould otherwise pack closely around it, said case being perforated, asat c', in the lower portion for the escape of the water. d is a stop forthe valve.

It will be seen that the construction of my improved hydrant is verysimple, that it is not liable to get out of order, and that it is simpleand reliable in opera-tion.

The construction and operation ofthe wastevalve are sameas in common useand form no part of my claim, but a section of such a valve is shown inFig. 8 for illustration of the same. The ball e is pressed against itsseat and prevents waste of water when valve fis open. The spring funseai's the ball when valve fis closed and opens'the discharge-passageg for the water remaining in the stand-pipe.

I am aware that a protective sheathing of sheet metal has been appliedover the lower portion of the rod of a waste-valve and over said valve,fitted in an independent part attached to the stand-pipe, as in PatentNo. 485,409, and I make no claim to such device, my invention being animproved construction of the main-valve case exterior to the standpipe,with an integral protective tube for the main-valve rod extending to thetop of the IOO stand-pipe and Containing the nut for operating thevalve.

I claim- `l. In a hydrant having a gate-Valve in a valVe-inelosing easeexterior t0 the standpipe and detaehably attached thereto, said caseformed with a protective cover for the valverod consisting of anintegral vertical extension of the Valve-rod stufng'box alongin eontactwith and bolted to the side of the standpipe, said Cover ehambered inthe side bearing against the stand-pipe for the rod and the stuffing-boxgland, and being extended to the top of the stand-pipe and having therod-aetu ating nut itted in the top substantially as described.

2. The combination in a hydrant, of the lXf'alVe-ease substantially asdescribed.
